Walker Yumasaki (遊 馬崎 ウォーカー, Yūmasaki Wōkā), like his female friend and companion, Erika, is a very passionate otaku and manga reader, although he doesn't share the same love for yaoi that Erika does. He and Erika are nearly always together. He also likes to perform torture by letting the victim to choose a light novel or manga, and carrying out the contents. He seems to be carefree and is usually seen wearing a wide dumb smile, but in reality he's a serious thinker. Like Erika he is very mysterious person. He is a member of the anonymous online gang Dollars and is also a member of Kadota's gang. In the later episodes, Walker was asked to remain inside the van for the invasion of the Yellow Scarves, because he would "stand out too much".
